JHA 450



JHA is a height adjustable joist hanger for supporting timber joists from timber members.

Material: Pre-galvanised mild steel

  • A galvanised joist hanger that provides great support with ease of installation.
  • Published performance values are based upon 3.75 x 30mm square twist nails being used throughout.
  • Wider strap provides more surface area on the supporting timber and allows increased nail spacing, enhancing the performance of the critical hanger-to-support part of the connection.
  • Minimum and maximum nailing schedules are stamped into the strap providing correct installation information for site operatives.
  • Speed-prong holds the hanger in position to allow easier attachment. The installer no longer has to try to hold hanger, joist and nail with one hand and swing a hammer with the other!
  • JHA270 range features a location tab which allows easier alignment of the hanger.
  • The model number and size is stamped into the seat of the hanger for easy identification, even after installation.
